0.8.6

New features

• Add the validate method to companions of refined types to accumulate
  errors with cats.data.ValidatedNel. To use this method, syntax._
  from the refined-cats module needs to be imported like this:

  scala> import eu.timepit.refined.types.numeric.PosInt
  scala> import eu.timepit.refined.cats.syntax._
  
  scala> PosInt.validate(1)
  res0: cats.data.ValidatedNel[String,PosInt] = Valid(1)

  Thanks to Howy Perrin!
  (#382, #384)
• Add the validate method using scalaz.ValidationNel also to the
  refined-scalaz module.
  Thanks to kusamakura! (#385)

New predicates

string

• ValidInt: checks if a String is a parsable Int
• ValidLong: checks if a String is a parsable Long
• ValidDouble: checks if a String is a parsable Double
• ValidBigInt: checks if a String is a parsable BigInt
• ValidBigDecimal: checks if a String is a parsable BigDecimal

Thanks to kusamakura! (#379)

Performance improvements

• Apply the optimization done in #334 also to macro calls that
  use RefineMacro.implApplyRef. Before this change, compilation time
  of e.g. PosInt(1) was one order of magnitude slower than 1: PosInt.
  With this change there is no difference in compilation times between
  these two calls. (#388)

Updates

• Update refined-cats to Cats 1.0.0. (#390)
